SILO.

Specification of Letters Patent.

' Patented May 22, 1917.

Application filed March 4, 1916. Serial No. 82,156.

To all whom it may concern:

Be it known that I, EDGAR J. ABBETT, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain useful Tmprovements in Silos, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in silos, one object of the invention being the provision of a reinforced concrete silo, the wall of which is composed of a plurality of segmental slabs or blocks of reinforced concrete, the meeting of joining ends of which form a ship lap joint, so that such blocks vor slabs may be readily set up, to form silos of various diameters, and to produce a rigid and permanent structure.

A further object of this invention is the provision of a silo, of simple, durable and comparatively inexpensive construction as compared with the wooden ones, and a silo which is thoroughly eflicient and practical in use.

In the accompanying drawings Figure l is a front elevation of acomplete silo constructed according to and embodying my invention.

Fig. 2 is a cross section on line 22 of F i 1.

Fig. 3 is a cross section on line 33 of Fig. 1.

Figs. 4, 5 and 6 are detail views. Referring to the drawings, the numeral 10 designates the base or foundation for the silo, and resting thereon is the main platform or floor 11, provided with the central drain 12.

The wall is composed of superposed layers of segmental blocks or slabs 13, each of which is composed of the metal reinforcement 14, and concrete 15, theedges 16 being formed to provide a ship lap joint, when the slabs are assembled. The bolts 16 are provided at each joint, and are carried in the end of the metal reinforcement, the threaded ends extending outwardly to re ceive the retaining or bracing hoops or hands 17 The metal reinforcement is com posed of the sheet metal frame 18 made of strips of metal, which support the sheet 19 of wire mesh, and thus reinforce the slab throughout its area.

Carried by the uppermost layer of slabs and attached by bolts 20 thereto is the roof framing 21, which rigidly supports the coniand being provided with the hook latch upon its upper edge to cooperate with the cleat 29, to hold the door closed.

The two parallel strips 30 of metal are supported exterior of the wall of the silo and in front of the doors, by means of the horizontally parallel stays 31 which are anchored to the wall, and the inclined braces 32. Openings 33 are provided in the strips 30, for the removable reception of the tubular rungs 34, each one of which is provided with the limiting nut 35 upon one end, and the pin-and-slot locking device 36 at the other end.

The rungs are so arranged that one is adjacent the door frame, so that when the door is swung outwardly to open position the hook latch will rest upon the rung and thus provide a rigid platform at each door open mg.

In order to facilitate the emptying of the silo, there is supported at one side of the ladder structure a vertical chute 37 whose lower end 38 terminates at a point above the ground to permit a wagon or other receptacle to pass therebelow, while adjacent to each door is an inlet opening 39, to permit the introduction of the ensilage therein to pass downwardly through the chute.

The upper and lower edges 40 and 4.1 of each slab is also provided with a-ship lap joint, so that one layer will interlock and thus produce a tight close'joint, and so that the entire structure will maintain the ensilage in the proper condition at all times.

From the foregoing description taken in connection with the drawings, it is evident that a durable and readily constructed silo is provided, and one in which the labor of filling and emptying is reduced to a minimum.

What I claim, as new, is

1. A silo, consisting of a wall composed of superposed layers or segmental reinforced concrete blocks or slabs, the meeting edges of which are connected by a ship lap joint, fastening means carried by each slab for disposition adjacent the circumferential joints of the Wall, and a plurality of retaining hoops attached to the Wall exteriorly thereof by the fastening means and adjacent each circumferential joint.

2. A silo, composed of layers of segmental" tion by the fastening means.

3. A silo composed of a plurality of segmental slabs having their adjacent sides and ends reduced to provide shiplap joints, a reinforcing element in each slab embodying a frame conforming to the contour of and arranged diagonally in the slab and in the reduced ends and sides thereof and a taut Copies of this patent may be obtained for five cents each, by addressing the a Washington, D. 6.

lap joints When the slabs are Wire mesh carried by the frame, bolts anchored in the frame in each slab and passing through the frames in the adjacent slabs at the joints thereof, and means for clamping the bolts in position. l. A silo comprising a plurality of segmental slabs each including a body formed of concrete having the adjacent ends and sides reduced to provide shiplap joints, a reinforcing element anchored in the body of each slab when it is molded and embodying an open-metallic frame conforming to the contour of and arranged diagonally in the body and in the reduced ends and sides thereof and a taut Wire mesh carried by the frame, bolts anchored in the frame in each slab and passing through the frame in the adjacent slab body at the joints thereof, hoops encircling the silo at the horizontal meeting edges of the joints and engagedby the bolts for bracing the slabs, and nuts engaging the bolts for clamping the hoops and slabs in position.

In testimony whereof I affix my signature.
